EZA-ST52AAAJ

Overview

The EZA-ST52AAAJ is a fourth-order low-pass RC (Pi) EMI filter circuit manufactured by Panasonic Industry. It features four channels with a resistance of 470 Ohms and capacitance of 47 pF per channel. The component operates within a voltage rating of 25 V and supports an operating temperature range from -25°C to +85°C. It utilizes a surface-mount 1608 (4021 metric) concave package measuring 4.00 mm in length, 2.10 mm in width, and 0.85 mm in height.

Feature Summary

• Integrates a fourth-order low-pass RC Pi network for effective electromagnetic interference suppression
• Provides four independent filtering channels within a compact surface-mount footprint
• Designed specifically for signal integrity maintenance on high-speed data lines

Applications

• Mobile device data line protection
• High-speed interface circuits requiring EMI reduction
• Embedded systems with sensitive signal processing requirements

Procurement Notes

Verify current availability status as the component may be subject to discontinuation or limited supply constraints. Confirm RoHS compliance details through official documentation before integration. Ensure sourcing channels provide genuine parts with appropriate traceability. Check for alternative packages if lead times are critical for production schedules.

Selection Notes

Select this component when designing circuits that require multi-channel EMI filtering for data lines. The 470 Ohm resistance and 47 pF capacitance values define the cutoff characteristics suitable for specific signal frequencies. Consider the 1608 package dimensions for PCB layout constraints and ensure thermal management aligns with the specified operating temperature range.

Part Context

This part belongs to the EZA-ST series of RC EMI filters from Panasonic Industry. These components are engineered to suppress noise in digital and analog circuits without significantly distorting the desired signal. The series offers various configurations tailored for different data rates and form factors, supporting modern electronic design requirements for compactness and performance.

Replacement Considerations

Consult official Panasonic documentation for verified substitute part numbers within the same series. Cross-referencing requires matching electrical parameters such as resistance, capacitance, and channel count. Verify package compatibility and thermal specifications before implementing any alternative components.
